"For those who miss TomTom"

Fully offline turn-by-turn navigational system, designed to be used in the car

Navigon is a turn-by-turn navigational system, similar to Google Maps. It's unique in that it's a "real" GPS app - instead of accessing the maps over 3G like Google Maps, you anticipate where you're going in advance and download the detailed map of that area. That way, even if you drop off the grid, the app keeps directing you like nothing's happened.

The interface is solid, and the voice prompts are loud enough to be heard over mild car noise.

However, I'd only recommend purchasing this rather expensive app if you plan on spending quite a lot of time driving somewhere with no signal. Getting access to live traffic updates isn't free (it's included in Google Maps, plus other comparable navigational systems), and you'll also have to pay to re-download maps when they're updated. Honestly, it's a decent enough navigational system, but the price of Navigon feels really out of line with where free technology is these days.

All in all a good navigation solution. Sadly for some time now, it doesn't show up as a choice anymore when launching navigation from the Google Maps app. The navigation is still superior to (and better presented than) TomTom and its derivates
